❓ FAQ

Yes. KA20509 matches C 14 179: 134 mm outer diameter, 162 mm fin diameter, 290 mm height, 17 mm inner bore and 67 mm inner diameter, with an axial seal. It also cross-references Fleetguard AF437K.

It is the fin ring diameter, not the filter body. The pleated body measures 134 mm outer diameter; the outer fin ring at 162 mm centres the element in the housing and adds rigidity. Both figures are needed to confirm fitment.

No. Cellulose pleated elements are not washable; washing damages the pleat structure and releases trapped media fibres. Replace the element and clean the housing bore instead.

KA20509 is the primary element only. Where the housing carries a safety element, fit the matching secondary cartridge as well so the intake stays protected if the primary is damaged.

Description

Product Overview

KA20509 is a primary air filter element with axial seal for diesel engines in light trucks, vans and Land Rover / LDV vehicles. It measures 134 mm at the body, 162 mm across the fins and 290 mm overall height, with a 17 mm inner bore and 67 mm secondary inner diameter. The envelope matches MANN C 14 179 and Fleetguard AF437K.

Key Features

Axial seal design — seals against the housing face rather than the bore, keeping unfiltered air from bypassing the element.
Finned outer body — the 162 mm fin ring locates the element centrally and adds structural rigidity under vibration.
High pleat count cellulose — large dust-holding capacity while keeping intake restriction low for consistent airflow.
Flame-resistant media option — meets intake safety requirements for vehicles operating near combustible environments.
Direct interchange — replaces MANN C 14 179, Fleetguard AF437K and Donaldson P181052 without housing changes.
